Help with identifying engine tapping noise
Hello guys,
I have this problem I've been trying to figure out for a while - when engine is warm, it's making distincitve tapping noise at idle, I think it can be clearly heard at the videos below. I checked how the bad TCT sounds like and it's a different sound to me, but I'd like to hear your opinions.
It's 2001 AP1, 170k miles on the clock, valve adjustment done 1k miles ago (they were a little bit tight before adjustment), not throwing any CELs, runs and drives good, except burning pretty serious amount of oil which I top up every time (I guess with that mileage on AP1 it's not so uncommon).
Cold start (not sure why the video is mirrored but that's irrelevant):
Idle when cold:
Idle when hot (after 30 mile drive):
Any input appreciated, thanks in advance!

Sounds normal to me.

Warmed up it sounds exactly like mine. This car has the worlds noisiest injectors and valves so as you move your head around the engine bay the sound is always coming from somewhere else lol I found a video on youtube that was basically a clone of this post. Sounded identical.

No, after the posts I just assumed everything is fine.
Good advice, I can make that happen and post it here by the end of the week

I am no mechanic and do not claim to have any mechanical skills, I would have someone look at that for me . . .Given that expense of something going wrong, something you could have addressed, I would have it checked by someone who is very familiar with these engines. Good luck and do update us on the outcome.
